ATTORNEY United States Patent arouse APPARATUS Ralph M.Faust-,WestchestenllL, assignor to Swift & Company, Chicago, 11]., a.corporation. of Illinois The present invention relates to aliquiddispenser having a roll serving both as an applicator and" a valve tostop the flow of liquid when the applicator is not in use.

Surprising as it may seem. the technological advances of our time havenot succeeded in replacing the glue pot and brush as' one'of the most"commonly used pieces of apparatus employed in various types of gluing.operations. Yet this traditional apparatus has many disadvantages. It isboth messy and wasteful.

To successfully replace the glue pot and brush a device must beinexpensive. It must be simple to use. There must be little or no wearand substantially nothing to get out of order even with hard usage.Preferably the manual operation employed in applying glue to a surfacewith the apparatus will be substantially the same as the movementordinarily made in wiping a glue brush across a similar surface. Animportant feature of the acceptability of such a device is whether ornot it leaks glue when not in use, for if it does it has the traditionaldisadvantages of being wasteful and of creating a mess.

The principal object of the present invention is to produce a devicethat has these desirable characteristics and overcomes the disadvantagesfound in other apparatus for doing the same job.

An important feature of the present invention is the simplicity of themanual operation involved in gluing a surface with it. All that isrequired is to run'the applicator roll across the surface to be gluedwith a slight pressure and an even coating of glue is spread across thatsurface. A release of the pressure such as occurs when the dispenser islifted at the end of a stroke immediately shuts olf the flow of glue.

A further object and advantage of the invention is that the quantity ofglue laid down by the roll may be varied depending upon the job to bedone, the characteristics of the glue, etc. Resetting the dispenser toapply a different amount of glue is a quick and simple operation whichmay be performed by the most inexperienced individual. Upon having beenreset the dispenser will spread an even coating of the desired amount ofglue with each stroke.

Other objects and advantages will be apparent from the followingdescription taken in conjunction with the drawings in which:

Figure 1 is an isometric view of an embodiment of the invention;

Figure 2 is a partial section taken at line 2-2 of Figure 1; and

Figure 3 is a partial section taken at line 3-3 of Figure 2.

The illustrated embodiment comprises an applicator roll, generally 10,mounted within a housing, generally 11. To housing 11 is attached areservoir, generally 12.

Housing 11 is made in two pieces held together by bolts 13. The housinghas an inner opening 14 to receive roll 10 with the opening 14 extendingthrough one side 15 of thehousing to form the mouth ofthe opening 14through which roll 10 projects. The shape of the mouth of opening 14 isthe same as that of a cross-section of roll 10 taken parallel to theaxis of the roll to one side of said axis.

Roll 10 has a pair of projecting shafts 17 and 18 to rotatably supportthe roll: within the housing 11. At each end of roll 10-is a raisedridge 19 having a knurled periphery. -In-the illustrated embodiment theheight of ridge 1 9 above the surface of the roll 10 is slightly lessthan ,6 of an. inch, but this may be varied in. other embodiments. Theheight of ridge 19 will have some effect upon the quantity of glue orother-liquid laid down by the dispenser.

At each end of opening 14 in housing 11 is a recess, 21 and 22-respectively, to receive shafts 17 and 18 and form bearings therefor inthe housing. As will be seen in Figures 2 and 3, recesses 21 and 22 areelongated in a direction normal to side 15 of the housing to permit therollv 10 to be moved into and out of the mouth of the opening. Theelongated portion of the recesses 21-and 22 are indicated by the numbers23 and 24, repectively.- a

Bores' 27 and 28 in housing 11 are normaltO'.Sld6' 15 and intersectrecesses 21 and 22 respectively. At least a portion of bores 27 and 28are threaded as indicated at 29 and 30. Within bore 27 is a plug 31, aspring 33, and a set screw 35 engaging threads 29. Similarly, bore 28has a plug 32, a spring 34, and a set screw 36. The ends of plugs 31 and32 ride on shafts 17 and 18 and under the urging of springs 33 and 34press the roll 10 into the mouth of opening 14 to provide a liquid sealacross the mouth of the opening.

Plugs 31 and 32 have risers 37 and 38 thereon which project through theinneropening in springs 33 and 34. When roll 10 is pressed into opening14 in housing 11, this movement will be stopped by risers 37 and 38contacting set screws 35 and 36. Thus the extent to which the roll 10can be pushed out of the mouth of open ing 14 and back into that openingmay be adjusted by changing the position of set screws 35 and 36 withre-* spect to the risers on plugs 31 and 32.

One end of reservoir 12 is screwed on to housing 11 as illustrated at41. The opposite end of reservoir 12 has a cap 42 threaded into thereservoir as illustrated at 43. A gasket 44 is used to obtain a sealbetween the housing 11 and reservoir 12, while a gasket 45 is used toobtain a seal between reservoir 12 and cap 42. The interior of reservoir12 communicates with opening 14 in housing 11 through a passage 46.

To operate the dispenser the reservoir 12 is filled with glue byremoving cap 42, which cap is then replaced to seal the reservoir. Toapply the glue to a surface the operator grasps the dispenser by thereservoir 12 which serves as a handle. Roll 10 is placed on the surfaceon which the glue is to be spread. A slight downward pressure on thedispenser pushes roll 10 out of the mouth up into opening 14 bycompressing springs 33 and 34. The applicator is drawn across thesurface which causes roll 10 to rotate within the housing. The rotationof the roll, plus the fact that the mouth of opening 14 has been openedby the inward movement of roll 10 causes the glue to flow out on andaround the roll to be spread across the surface traversed by the roll.At the end of the stroke the relieving of the pressure on roll 10results in the roll again sealing the mouth of opening 14 under theurging of the springs 33 and 34.

It will be noted that this movement in applying glue is substantiallyidentical with that usually used in drawing a brush that has beenpreviously dipped in glue across a surface. If the amount of gluedispensed is excessive, the set screws 35 and 36 may be moved closer tothe ends of plugs 31 and 32 to further restrict the movement of roll 10with respect to the mouth-of opening 14. Similarly, increasing themovement of roll 10 with respect to the mouth of opening 14 by suitableadjustment of the set screws permits the application of a greateramountof liquid from the dispenser.

It will be obvious that the described invention can be used for numerousliquids other than glue. The description of a specific embodiment wasfor the purpose of complying with 35 U. S. C. 112 and should not beconstrued as imposing unnecessary limitations upon the appended claim.Variations will be apparent to those skilled in the art, and suchvariations are deemed to be within the scope of the invention to theextent that they are not excluded by the limitations of the claim.
